In Evil Dead (staring Bruce Campbell as Ash), there is a scene where a young woman, Ash's girlfriend is out in the woods (which are of course, possessed by an evil spirit), and she is attacked by plants. When I say attacked, I mean, at first she is dragged through the woods, screaming bloody murder all the while. Then, the plants wrap around her like bondage a la Japanese Tentacle Porn, and proceed to tear her clothes off. In a final act of dendro-human lust, one large, meaty tentacle slides up her skirt and she half moans, half screams, making the viewer unsure if she is in pain or pleasure (disturbing, yes, but quite funny). Anyway, I believe this is classified as dendrophilia.
As a side note, I once knew a guy, who whenever we passed a tree with a hole in it screamed out, "THE MARK OF A DENDROPHILIAC!!!"
